Miktex users which updated to the newest xetex engine (version
3.1415926-2.4-0.9998 (MiKTeX 2.9)) report problems with subscripts
in math.




gives the error

! \textfont 197 is undefined (character .5).
l.6 $a_{b1}$
If one continues the output looks ok.

The same document compiled with TL13 gives no error but there is a
suspicious missing character message in the log which imho could be

Missing character: There is no Dž in font

On a miktex without the new xelatex engine but the same unicode-math
version there is no problem.
